SPECIFICATION forming part of Letters Patent No. 298,499, dated May 13,1884.

Applicalion filed September 21, 1883. (No model.)

To @ZZ whom it may concern..-

Be it known that I, ORLANDO M. POND, of Independence, in the county ot'Buchanan and State of Iowa, have invented certain new and usefulImprovements in Slate Frames; and I do hereby declare that the followingis a full, clear, and exact description thereof, reference being had tothe accompanying drawings,and to the letters of reference markedthereon, which form part of this specification, in which- Figure lis aperspective View of one oorner of my improved slate-frame, showing aportion of a slate secured therein. Fig. 2 shows two sections of theframe. adapted to form a right-angle corner. Fig. 3 is a modification.

This invention relates to frames which are designed for school-slatesand other purposes; and it consists in a frame which is composed ofstrips of pasteboard prepared and put together in the manner which willbe fully understood from the following description, when taken inconnection with the annexed drawings. Each one of the end and side barsof the frame is composed of three narrow strips of pasteboard. Thestrips A A are of the same width, and are cemented to an intermediatestrip, B, which is narrower than the stripsA A', for the purposeolileaving a groove, a, adapted to receive the edge of the slate G orother slab. The side and end bars ofthe frame are united by lappingjoints; or, if desired, each portion, A, A, and B, may be madecontinuous, as shown in Fig. 3, so that the con ners of the slate willbe solid. Vhen the corners are made with lap-joints, I construct eachcorner as follows: The end ot' the strip A of a side bar is extendedbeyond the strips A B, a distance equal to the width of the strips A A',so as to form a lapping portion, b, leaving a portion, c, of theintermediate strip, B, extended a short distance beyond the shoulder d,at the terminus of the strip A. The end bar is constructed to match theparts b c d and form a double lap-joint, the end bar being secured tothe side bar by means of any suitable cement. It will be observed, byreference to the right-hand portion of Fig. 2, that the ends of thestrips A B are both extended beyond the shoulder e at the end of thestrip A, a distance equal to the width of the strips A A. Thus it willbe seen that one end ofa side bar is a counterpart of one end of an endbar, both ends matching exactly, so as to form, when cemented together,a substantial joint, which I prefer to cover with leather D, or othersuitable material cemented over the joint, which not only gives a finishto the cor-v ered with leather or other soft material, substantially asdescribed.

In testimony that I claim the foregoing as my own I here affix mysignature in presence ot' two witnesses.

ORLANDO M. POND.
